Long-lasting AASHTO M249 Reflective Thermoplastic Road Marking Paint for Safe and Bright Road Markings

Product Description

AASHTO M249 thermoplastic paint is a specialized pavement marking material that conforms to the standards set by the American Association of State Highway and Transportation Officials (AASHTO) under the M249 specification. It is used for creating durable and reflective road markings, such as lane lines, crosswalks, and traffic symbols, on asphalt and concrete surfaces.

Applications

• Highways and freeways.
• Urban streets and intersections.
• Pedestrian crosswalks and stop lines.
• Parking lot markings and traffic symbols.

Performance Features

• Adheres well to asphalt and concrete surfaces.
• Offers vibrant and fade-resistant colors (white and yellow are standard).
• Long-lasting retro-reflectivity enhances safety for drivers at night.
• Resistant to cracking, chipping, and peeling.

Components

• Binder Resins: Provides adhesion to road surfaces and durability.
• Pigments: Ensures bright, visible colors (e.g., titanium dioxide for white, lead-free pigments for yellow).
• Glass Beads: Improves reflectivity.
• Fillers and Additives: Enhance texture, skid resistance, and performance characteristics.

Key Features

1. Thermoplastic Material:
   It is composed of thermoplastic resins that melt at high temperatures (180°C to 220°C) during application and solidify quickly upon cooling.

2. Durability:
   This paint is highly resistant to wear, weathering, and UV exposure, making it suitable for high-traffic and harsh environmental conditions.

3. Retro-Reflectivity:
   Embedded glass beads provide excellent reflectivity, enhancing visibility at night and during adverse weather conditions.

4. Fast Setting:
   The paint cools and hardens rapidly after application, reducing downtime and traffic disruption.

5. Safety and Compliance:
   Designed to meet safety and environmental standards, modern formulations are lead-free and have reduced VOC emissions.

Detailed Process of Thermoplastic Marking Paint Construction

1. Road Cleaning

Before operation, the nearby area must be cleaned to ensure that there are no impurities such as oil, water, fallen leaves, weeds, ect., so as not to affect the adhesion effect, flatness and reflection effect of the line.

2. Set the Point and Mark Line

In the process of sampling, the calculation and measurement must be carried out in strict accordance with the construction drawings. Measure the several lanes that need to be drawn on the road, set the point, and then mark it with a stone pen. Use titanium dioxide powder to glue the rope for the elastic line. After the rope is removed, it will be corrected and improved to ensure that the line shape is clear and accurate.

3. Apply the Primer

The lower coating is a common binder in hot melt marking construction. It is applied to the highway road surface, which can make the hot melt coating better adhere to the road surface.

4. Spray the Paint

Before construction, first check the relevant coating equipment. Then heat the paint.

When the trolley moves forward, the paint will form a coating film on the road, and a layer of glass beads should be sprinkled on the coating film during the coating process.

When the trolley moves forward, take the reference line as the ruler, control the thickness and width of the line, and ensure the coordination, clarity and smoothness of the line connection between the straight line and the curve.

Note: During the coating process, in order to avoid the sedimentation and separation of the paint, it is necessary to stir the paint frequently.

5. Check and Correct

After the coating is completed, check and correct the line shape, check the spread of glass beads, etc.

After confirming that it is correct, the construction site will be cleaned up.

After the line is dried and hardened, the relevant construction equipment can be transferred, the safety facilities can be dismantled, and the traffic can be opened.
